Hi, did you get the leds to work? Can you also include the SET_LOW() and SET_HIGH() functions?
I think the #include file "ws2812B.h" only has the extern declaration of the functions, right?
Can you share the complete example?
Thank you

Hi, can anyone explain me how to retrieve the result of the aes_encrypt function, please?

I tryed to follow the example of the library, but i don't understand how to get the encrypted data from the handle function, thanks.

The library is inside the SDK and its name is aes.h.

typedef void (aes_func_result_cb) (uint8_t status, const uint8_t aes_res, uint32_t src_info);

Hi at all,
there is a guide step by step for how to configure keil to correct compite the ble_simple_peripheral?
When i double click on the file "ble_simple_peripheral.uvproj", keil starts and display this form, i selected "Migrate to Device Pack", it's right?

After this selection appear this window that i close because i don't know what to select, it's right?

After that keil asked me if i want to migrato to use pack device, i selected Yes, it's right?

Here i selected this device, it's right?

This window confirm the migration

Then when i try to compile there are a lot of errors

I'm a beginner, please, can anyone help me?
Thanks a lot

Hi at all,
I'm a new developer with this chip, i saw the "ble_simple_periphear" example in the "security encryption" for BLE, it's sufficient to setup the parameters like this to have an encrypted connection?

I need to prevent sniffing to my information.

gap_security_param_t gap_security_param={
.mitm=false,
.ble_secure_conn=true,
.io_cap=GAP_IO_CAP_NO_INPUT_NO_OUTPUT,
.pair_init_mode=GAP_PAIRING_MODE_WAIT_FOR_REQ,
.bond_auth=true,
.password=0,
};/gap_security_param/

I searched i other posts but i didn't find informations.

Thanks to all
